( #3333=superdoc: print w/replies, xml ) Need Help??

The hash won't preserve the sort order from the SQL so you have to retain that in an array which I have called @top

#!perl use DBI; use strict; my $DBH = get_dbh(); my $sql = 'SELECT queue_name,jobs_pend,jobs_run FROM queues ORDER BY jobs_run DESC'; my $sth = $DBH->prepare( $sql ); $sth->execute(); # input my %table = (); my $recno = 0; my @top = (); while (my ($name,$pend,$run) = $sth->fetchrow_array){ my $key = ($recno++ < 5) ? $name : 'other' ; $table{$key}{'pend'} += $pend; $table{$key}{'run'} += $run; push @top,$key unless ($top[-1] eq 'other'); } # output for my $key (@top){ my @col = ($key);# col[0] $col[1] = $table{$key}{'pend'}; $col[2] = $table{$key}{'run'}; printf "| %-25s | %3d | %3d |\n",@col; }

Update : you could just use an array without the hash

# input my @top = (); my $max = 5; my $recno = 0; while (my ($name,$pend,$run) = $sth->fetchrow_array){ my $ix = ($recno > $max) ? $max : $recno ; $top[$ix][0] = $name; $top[$ix][1] += $pend; $top[$ix][2] += $run; ++$recno; } $top[$max][0] = 'other'; # output for (@top){ printf "| %-25s | %3d | %3d |\n",@$_; }
